On a Manchester vibe:
Atlantic Fish Bar, Chorlton - Best in the area imo, high through put of customers so always freshly fried goods, lovely fish, decent chips, portion big enough for two (the missus and I share a fish, chips and mushy peas and struggle to finish it), resonable pricing (for SW Manchester)
Thye also endeared themselves to me when asked by a wanky Chorlton-ite (there are a few Middle-Class hippy/vegan wannabes around here) where they sourced their fish the gentleman serving pointed to the sign and said, "The Atlantic, love, where else?"
